I have easy to follow and thorough step by step tutorials "do it yourself" (DIY) videos to help you with your broken lawn and garden equipment including snowblowers and zero turn mowers.
I do my best to teach you how to easily diagnose problems the fastest, quickest and most efficient way with real repairs beyond just replacing a spark plug. These tips are for both the homeowner and shop owner.
Whether it be a handheld, two stroke, two cycle engine like a chainsaw, weed eater, weed whacker, string trimmer, grass trimmer, line trimmer, hedge trimmer, strimmer, brush cutter, leaf blower, or four stroke, four cycle units like a lawnmower, wood splitter, lawn tractor, zero turn mower, snowblower, pressure washer, generator or a ride on mower that needs parts installed or replaced, I’m your go-to guy.
My favorite brands of spark plugs are NGK and Champion and are the ones I recommend.
I’ve been a small engine mechanic for many decades and also run my own repair shop so my videos are loaded with tips and tricks that I have learned and want to share with you. You will also find many tool and product reviews from top brands on my channel as well.
I have the largest Small Engine Repair Video Library on TH-cam and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!

After fooling around for 3 hours with a car jack the damn thing did not budge but after I saw your video it came off in 20 minutes. Thanks
Thank you so much! Two hours of screwing around in trying to remove 'er and then I find this video.. Already threaded so 10 minutes later it's free.
Thanks for the assistance.
I ended up using the two prybar and hammer method, but I wouldn't have figured it out that the shaft was tapered without your help.
If the taper hadn't released, I was on my way to the tap and die set!
Great video. Same technique is used on Polaris ATV to remove the primary clutch from the engine, but polaris already has the threads in the clutch for the large screw in bolt. I have removed the bad armature from my older Generac L4001, I only wish I could come up with a sutiable replacement on this apparent no longer available replacement part. Complete engine awaiting repair if I ever manage to find an armature. Thanks again for the clear, concise video.
Great video buddy appreciate it. I would have never gotten it apart without your help
No problem 👍
Thanks, I've been trying to covert my generator into an engine for my go kart for sometime now. Had no clue how to get the armature off. Thanks again!

I am a generac master tech per factory spec the recommended way to remove the armature is striking with a rubber mallet rotating and repeating until it comes loose
Thanks I had no idea how to get them apart save me hours of figuring it out . Gave you a thumbs up and subscribed .
Donny,
Very well done, thank you for sharing. I just finished using your technique, including tapping the center of the armature. If you ever find yourself in MA/RI there is some cold beer or hot coffee waiting for you. Subscribed.
Worked a treat, saved me a lot of head scratching. Thank you
Thank you so much! I have a Winco 4PTH - 3M/L10 it said to use a hammer. No-go, but a 3/8" x 24 tap fit PERFECT. Got a grade 8 3/8 x 24 and cut a gutter nail head and end off - WHAM! There it is! Now I can replace the governor :)
works great. make sure to use the sizes he says in the vid, else u may break the rod if it is smaller. thanks donyboy
Awesome, have two generators I need to take apart, thanks for this video.
excellent advice as always from this you-tuber
thanks Tony!
Oh hey donyboy73 I guess you did have a video on how to get the engine off of the generator. Thanks for sharing.
thanks for watching, make sure to subscribe
thanks , 14 hp vanguard , no threads . did just the way you showed and perfect off in 5 minutes , thanks so much
Thank you for putting this video up! Really helpful.
thanks for watching gus
Thx. This video helped allot. Now I can get my project moving along. God bless.
@RockinGuy1994 lol, i thought after, what if the camera was off, which has happened before, but i was happy it turned out good
Mr. Donyboy thank you very much, from Venezuela!!!!!!
+JDBD83 you're welcome
Thanks Donyboy, this was very helpful. Watched another video on chainsaw carb clean up few months back. thanks for your videos.
Thank you mate .. great advice .. and you have a really positive friendly manner .. I will you well.
Rory.
thank you very much it helped me to open my alternator.lloyd australia
This worked like a charm, thanks!. Btw, I have a Coleman PM0435005 and the fan (0063406) seems to have ripped itself to shreds. I cannot for life of me find a replacement. If I just remove the fan would strapping a box fan to the chassis dissipate the heat enough to make this a usable product again or am I screwed? Are there any work-arounds, 3d printed parts, aftermarket, etc??
Don!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thank you for this video, it really helped me out
I showed my buddy what I did and he was impressed
I was given a generator with a seized Briggs and Stratton engine and was thinking of replacing it with a Harbor Freight engine. After getting the armature off, I used a copper bar and a hammer to drive the piston down. The engine freed up somewhat and so I tore it down completely. The rod and crank were not that bad. It looks like to piston was what had it seized. Any ideas why? Thanks again for the video.
It just takes that one time where not enough oil coats the cylinder wall where the rings make contact sliding up and down, either because the oil level was low, or was run mistakenly without oil after an oil change. On a brand new engine it is always a good idea to put a squirt of oil into the spark plug hole before starting. I hope this was of some help.
I saw this video 4hours too late ☹️😂 broke mine and it was the exact same model. Thanks for the genius tip tho!
Great video. Do you have any suggestions on how to put the armature back on the tapered shaft? I torque mine down to the specs in the manual but the brushes do not line up with the slip rings. The armature needs to be seated another 1/4 inch onto the shaft but I don't know how to make that happen. Any help would be appreciated.
Threading was easy as i had a tap but no luck snapped the bolt off inside so threads were good she just didnt want to give up
You just saved me some money! Thanks
Thanks for the video, I have an armature that has a portion of threaded bolt sticking out by about 0.5 inch. Do you have some advice for this? The threaded rod appears a little loose side to side but will not come out! Any help appreciated!
kool vid thanks, always nice to get new mechanical ideas for future use.
Ferd
This video was a great help thank you
mr. donyboy thank you very much, God bless you
+Radix Kurniawan you're welcome
No luck with removing the armature on my Generac 7500EXL. Also tried your dead blow hammer method while pressure applied with the bolt/rod. Also, tried after soaking overnight with penetrating oil inside the armature shaft and on the taper shaft between the motor and the armature fan. Then I tried striking a longer 3/8" threaded rod with a sledge hammer while prying outward on the armature fan. Still no luck. Any other ideas? Thank you for the excellent videos.
Hi, are there any generator armatures that are screwed in or are they all pressure united? Thanks for the video.
they are not screwed on the engine, only a bolt at the rear of armature that bolts into crankshaft
I have an onan 6.5 on my service truck and in my RV. I have a few 4.0's loose. when I rebuild them, I take a 1/2 to 3/4 filled 2 liter bottle and wedge it under the armature when I pop it. the water acts as ballast so it doesn't shoot out. you want it lightly wedged under. never had a problem.
I have a 10kw Briggs and Stratton all house home generator. I even had a service tech come out twice a year to maintain and check it so it would always be ready.
WELL, this guy wasn’t doing me any favors because the first major storm and power outage it died after 20 minutes of use. The motor and Genny has only 20.5 hours on it so you can imagine my frustration. I saw pieces of rubber all over inside the protective cover and I smelled Natural Gas very strongly. To make a long story short. The guy pulled out the protective insulation that sits on top of the Generator between the Gen/ armature part which gets pretty hot during use. The gas lines are a foam type rubber and the lack of insulation allowed the lines to break down and fail. ( this all the pieces of rubber)
My question is this if you would be so kind to give me your professional opinion:
Can I clean out the interior well and replace my gas lines with a solid black gas pipe type? The engine runs perfect, well it was up until in no longer got any fuel.
I’m semi-handy and I have a lot of tools. I’ve done my own car repairs for many years. However, I wonder if you think it’s an ok idea to re-pipe the lines that way or should I use the same type and just re-insulate the lines against the heat that ate the other lines.
BTW, as soon as I called my service guy and told him what happened, he decided to take the LOW road and say that I must have pulled out the insulation blah blah blah.
Needless to say he never stepped foot on my property ever again. Gosh I hate cheaters and liars. There is nothing less honorable than a liar.
So what do you think?
I’ll pay you to do it all if your anywhere close to me. I’m in Massachusetts on the South Shore??
Your probably half way across the country huh?
Anyways, thank you for your informative page and your time.

great video as always, keep up the good work
I have an 8750 black max generator with bad winding's. I ordered a complete rebuild for the alternator but it came with 3 wires coming off the winding's (2 black and one white) they are not labeled. The original winding's had 4 wires. (blue red white brown) and the rotor has a the studs the wires attach to but there is no stud for L2. Did I get the wrong parts? or is there a way to deal with this. Thanks Paul
I have a question about the generator is it possible it remove the armature without taking the stater off
good job and great tip
thanks James, have a good weekend!
There you go, haha glad I looked this up!
nice vid
Great video !!
gracias
Cool, I learned something new! How can you tell if an electric motor is bad or if an armature is bad. Can a TH-camr rewind a motor or you need a special machine for that? Thanks for making the videos!
good tip there.
Now if I could find some use for a perfectly healthy briggs motor with a ridiculously specialized tapered shaft.
How we remove it here in Nigeria, is by unscrewing the center bolt out a little and tapping the head with a mallet, and will pop out just fine.
thank you donyboy73
I even jumped when that armature poped off. lol
great info.
Koolbeans love the rope ideal to!!!!
Thanks
AM ATTEMPTING TO REMOVE AN ENGINE OUT OF GEN TO USE IT ON MY AIR COMPRESOR DO U THINK THE SHAFT OUT OF GEN FIT IN TO A BELT PULLEY? HAVE U EVER TRY TO USE PRESURE AIR
You kidden hitting crap with a hammer is how i got my master mechanic certification
Thanks ,buen trabajo
gracias amigo
Thanks A lot....
yes!
@babongo thank you
Hi, CAN you do a video on how to 'flash the field' on a Generator rotor ?
yes I will
Adding anti-seize to the shaft defeats the purpose of the 'engineered taper' on the shaft. The taper on the shaft and the corresponding female taper on the rotor are, as their name implies, engineered to make for a jam fit between the two parts. You can find this type of connection on drill presses (Jacobs taper #1,#2, or #3) on the tie rod ends of vehicle steering systems and many other points of connection where power must be transmitted thru the connection. Putting anything on the surfaces will possible render the connect less than reliable. the connection is SUPPOSED to be tight and difficult to get off. One way to keep from having a surprise loosening when tightening the bolt is that once the bolt is tightened sufficiently to create a good amount of resistance, take a steel hammer and smack (that's a technical term) the end of the bolt head sharply and the rotor mass will drop off into your hands. Easy Peasey.
Worked good for me beating it didnt work
Thank you
"she popped all of the sudden. I wasn't even expecting that"
-Dony 'no longer a boy' Boy73
Thanks! My Briggs just threw a rod! Need a new motor.
Great video. It would be even better if you show the end of the rotor after it comes out so we have better idea what we dealing with. Thanks anyway, very helpful.
Do you have a video of putting one back on?
Thank you!!!
haha, wow Good idea! just like a Pully remover!
Thank you !!!!!!!! I just sub.....
thanks
donyboy73 By the way, I made the tool just like you suggested ,,,,It worked just like a charm !!!! The generator is a Champion, pretty much the same... :)))
I like it it works
you are a good boy!
Just take it on balanced surface, and start hammering with the wooden stick on armature. the job will be done easily :)
thanks good video
Just replace the original long bolt and thread it a bit not much and hold the armature , punch the headbolt with a chipping gun fast and it will fall easy .... people do compllicate themselves.... the key is heavy vibrations and it will pop off right away ...
+Saul Castrejon - If you damage something, how are you going to get parts? I have an " Older " Generator, his method is the way to go!
Jordan Bronson while you are concerned and you should be ! about damaging parts , you will not believe me you are not moving the armature 6inches from the shaft to cause damage. The slightest thousandths of an inch that move will separate the armature from the tapered shaft. Tapping a thread and using a long bolt is not many people can do and its time consuming , use the same bolt that holds the armature leave it a bit loose and hit it one or 2 times with a chipping gun hold the armature with your hand and it will fall off. The bpm “impact” of the chipping gun wont hurt the crank “shaft” . Just my .02cents give it a try you wont be disappointed
@spelunkerd thanks
Terimakasih kawan.
muito bom!!!
depends on the mechanic
I need to get a tapping set
Hello, I'm very curious. Does that rotor have a permanent magnet. If there is no magnet, where is DC current given to the rings on the rotor. Greetings. I am from Turkey. Do you know Turkey.
Thanks
Awesome tip that really works!
Spent about 3 hours today fruitlessly trying to figure out how to remove a Briggs and Stratton engine from its induction generator rotor.
Tried your tip and all done in just 15 minutes and no damage, thank you so much, your a star!
the older homelite i bought off craigslist for 35.00 dollars has a briggs 1970's on it wasn't locked up after pulling the gen and getting into it it had never been ran and it had some kind of stop on it I guess for shipping it . have you ever come across anything like that. it was around the shafted I could have just cut it but your trick worked great. model e4000-1 are these good gen and the carb was bone dry never had gas in it.
Hmm the difference in terminology between our language annoys me. :D To me, a bolt("bult") is a metal rod without threads, that's used to fasten things. If it has threads, it's a screw. But in english it's clearly different.
hay dony i need help with my echo ht lead i want to know if it unscrews off the coil because i want to put a new lead on cause the old one is cracked and i want to replace it?
@donyboy73 damm ill hace to check if it is what can i do iv already tryed heat shink and the cable didnt move.
could i rip the cable out and put a new one in or wont it work?
@donyboy73 ok ill try that how do u join it with a nail or a screw? ill have a look at myne tomorrow case some unscrew iv seen one inn ur vids.
Great tip on the puller. I wouldn't have known that the armature was on a taper. Is there usually a shaft key involved or just the bare taper? If it is the taper alone that is transmitting the power to the rotor shaft, then I would be a bit leery of putting any lubricant other than light machine oil to prevent corrosion. The taper is meant to lock together.
I just watched your promo video. I think that you have one of the most clean and professional looking channels I have seen. I am now subscribed.
Hi Guys
First, thread the inside end of your rotor tube with the appropriate size tap and find a suitable bolt with a good amount of thread. Stand the Generator vertically with the rotor at the top. Wrap a good amount of pipe tape on all the threads of the bolt you found. Fill the rotor shaft hole with water. Start the bolt into the end of the rotor shaft and using your favorite electric impact tool, run the bolt in fairly quickly and the hydraulic pressure will pop the rotor off the end of the crankshaft. Works every time. If its leaking around the threads allot, put more pipe tape on your bolt.
Cheers
Willy
You should Support or cushion the Rotor underside so it will come to rest on a padding..!
@BriggsMower what i do is solder them together, or get a new 5mm pice of wire and solder it to the old wire, then cover it with heat shrink, like 2 to 3 layers
Why does this screw usually break, especially when it is loaded with an external fan, I could not find the solution, can you help me?
It is not armature .. it is rotor ... the stationary winding is called armature..
Nice demo, Dony.
donyboy really thank you so much for your videos brother you r a genius p.d.:i live in mexico jaja saludos!!
Thanks! I'll be doing this soon and this is extremely useful. I have a question though. Have you ever re-wound an armature like this?
